Condensation polymer - Wikipedia

Condensation polymer - Wikipedia

In one type of polymerization reaction, a series of condensation steps takes place whereby monomers or monomer chains add to each other to form longer chains. This is termed "condensation polymerization," or "step-growth polymerization," and occurs in such processes as the synthesis of polyesters or nylons.

In the gas phase polypropylene polymerization process 70%–80% of the heat is removed by condensation of propylene and subsequent vaporization of the liquid propylene in the reactor. The design amount of condensation was limited to about 17% of the circulating gas by an existing patent.

Polymerization of Nucleotides

Polymerization of Nucleotides

Polymerization of Nucleotides (Phosphodiester Bonds) Nucleotides are joined together similarly to other biological molecules, by a condensation reaction that releases a small, stable molecule. Unlike proteins, carbohydrates, and lipids, however, the molecule that is released is not water but pyrophosphate (two phosphate groups bound together).
